I owned a QL before I had enough money to buy an Amiga 500. Although the QL wasn´t a commercial success, it was the first "home"-computer with a 68k-CPU and preemptive multitasking (QDos). The QL has also a really cool inbuilt network (you can connect up to 64 QLs, no additional software needed) and a great Basic on ROM (SuperBasic).

And there is still a very active community with traders, commercial software and a magazine (QLtoday).

I will be on the show and present AmigaOS4.1 to the crowd. So every Amiga-User is welcomed

@wawa: Yes, the codename for the computer was "LOKI". The plan was to build a Sinclair Spectrum successor with custom-chips and with Amiga-like graphic-ability. But after Amstrad bought Sinclair they quit the project (as well as the Sinclair QL).
